9 Claims.

The present invention relates to improvements in valved dispensing capsor heads for siphon` or pressure bottles of the type commonly used forcarbonated liquids.

An object of the invention iS the provision of a Siphon head ofattractive design, which readily lends itself to comfortable singlehanded dispensing koperations and further embraces novel features ofsafety. l

Another object of the invention is the provi- Sion of a Siphon head inwhich the actuating mechanism is entirely enclosed, thereby eliminatingpossible premature discharge of the contents.

A further object of the invention is vthe provision of a siphon headwhich may be formed of any material suitable for die casting into whichportions formed of a non-corrosive metal may be inserted.

A still further object is the provision of a siphon head which isreadily demountable, the

valve mechanism being rendered easily accessible by removal of the headfrom the bottle.

Other objects andfeatures of novelty will be in part apparent and inpart pointed out during the course of the following description.

The usual Siphon head construction embodies a neck-like portionextending above the body of the head and having an outwardly extendingoperating lever connected thereto. The usual siphon head mechanismreceives much hard usage which sometimes damages the relatively softmetal of which the heads are constructed. Filling bottles havingweakened heads with highly charged liquids creates the danger ofexploding during both illing and using. In the present construction Ihave provided means for completely enclosing the operating mehavnism ina manner to prevent damage thereto. Such construction lends itselfreadily to easy manipulation.

Referring to the drawing and Fig. 2 in particular, the Siphon headcomprises a body portion Ill which may be formed of any materialsuitable 5 for die casting. In general practice siphon headsV are.manufactured from a material which is impervious to the corrosiveeffect of the usual content of the bottle. Such material is relativelyexpensive. With this feature paramount, the 10 present constructionprovides for only those surfacesin direct contact with the contentshaving a protecting covering of a more expensive noncorrosive materialsuch as block tin, as will be more fully described presently. 15

The body portion Ill is provided with a depending annular attachingflange II or skirt having internal screw threads I2 adapted to engage anexteriorly threaded split attaching'ring I3. The ring I3 is provided' onits inner surface with an 20 annular bead I4 for engaging the shoulderedfinish I5 of the usual siphon bottle. In securing the head to thebottle, the usual delivery tube I6 carried by a stopper I1 is placedwithin the bottle. An annular ange I8 on the stopper ex- 25 tends overthe sealing surface or rim of the bottle and provides a seal when thehead is secured in place. The split ring I3 is placed about the neck ofthe bottle and brought into threading engagement with the threaded angeIl where- 30 upon rotationof the head and ring in opposite directionscauses the bead Id'to be drawn against the shoulder I5, therebycompressing the flange I8 between the rim of the bottle and the Siphonhead to form a gas-tight seal.

' A hollow housing I9 extending upwardly from the body I0 provides acylindrical chamber 20 within the body in axial alignment with the angeII and bottle opening, into which the valve mechanism is tted. Anoutwardly and downwardly curved spout 2| formed'on one side of the headis provided with a passageway 22 which is in communication with thechamber 20 and serves for filling the bottle and discharging thecontents thereof in the usual manner.

A liner 23 formed of block tin or a similar non-corrosive metal in theform of an inverted cup, is forced into the chamber 20, the wall sur'rounding the open end of said cup being flared outwardly at 24 to form aflange against which the flange I 8 of the stopper Il' bears when thehead is assembled on the bottle. A liner 25 of Similar material withinthe passageway of the spout is suitably connected to the liner 23,thereby preventing any possible contact of the gas or 55 liquid withmetal which would have an injurious eect thereon.

The valve mechanism comprises a stem 26 or headed bolt which projectsinto the chamber 20 at right angles to the vertical axis thereof throughan opening 2l in the wall of the housing I9 and liner 23 diametricallyopposite the passageway 22 of the spout. The inner end of the stein isprovided with a head 28 threaded thereon which carries a seating member29 for closing the passage 22. head 2B by a beveled tongue and grooveconnection 29a and is readily removable should it .become worn and failto properly close the .passage 22. The valve head is maintainedinseatingposition by means of a spring member 3Q shown as being formed ofresilient rubber and disposed about the stem 26 between the head andYwalll of the chamber. gasket around the opening 2l and prevents theescape of pressure therethrough.

Means forA operating the valve mechanism comprises a covert! or hollowshell shaped longitudinally to .conform with the body portion andsubstantially rectangular in cross-section. Figs. l, 5 and 'l illustratethe general conformation of the cover. The cover is provided at one endwith a depending apron 32 having an aperture 33 near its upper end4forthe reception of the spout 2l. The lower end. of the apron is curvedhorizontally to conform generally withthe diameter of the skirt Il andprovides a finger gripping surface whereby the valve may be operated.When the valve is in closed position. the apron is spaced l from thebody of the head to permit suincient operating movement. A filet 32formed on the apron beneath the opening 33 extends outwardly in thedirection of the spout and provides a linger guard which preventspinching the ngers between the apron and `spout as the cover returns tothe closed position.

The cover 3| is adapted for limited sliding movement longitudinally ofthe spout and is provided with a pair of vertically disposed parallelbearing surfaces 35 within the cover on each side thereof adapted tobear against corresponding surface 3S formed on either side of 'thehousing I9. The bottom edge 3'! of the downwardly extending sides of thecover 3l lies in matched relation with an upwardly facing surface 38formed1 onthe'bodyA Iii. The meeting line of the surfaces 3l and 38 liesin the plane of the valve stern .26, the juncture of body IE! and cover3| on the side opposite the spout forming a well to permit free movement.of the outer end of the valve stern. The'valve is actuated by means ofa lug 4U extending downwardly into the path of the stemuiZE and having abifurcated end 4I 'or fork which straddles said stem and bears againstthe head thereof.

The cover 3l `is held in place by a retaining screw 42, threaded into aboss formed on the body Ill, and a slot 43 in the cover 3l. AnopeningMis provided opposite the head of the valve stem, and in alignmenttherewith to permit easy adjustment thereof;

When it is desired to discharge the contents of the bottle the bottlemay be grasped around the neck, the 'fingers overlying the apron beneaththe spout and suicient pressure exerted to move the apron toward theflange ll. 'This movement of the cover 3! causes the valve stem 2S to bedrawn outwardly, thus placing the chamber 20 in communication with thespout 2 l Such movement of the cover is illustrated by dotted lines inFig. 5,

The member 29 is secured to the.i

The rubber further servesas a.-

It will be noted that the valve member 29 may be readily removed andreplaced without dismantling the head or removing other parts thereof.Further, the entire valve unit may be replaced without disturbing thecover. These and other features produce a simple and economic articleembodying a wide margin of safety by the elimination. of the usualprojecting operating lever.

Modications may be resorted to without departing from the scope of theappended claims.
